qlcnic(7D) Devices qlcnic(7D)NAMEqlcnic - QLogic P3+ 10 Gigabit Ethernet Driver
SYNOPSIS
/dev/qlcnic*
DESCRIPTION
The qlcnic 10 Gigabit Ethernet driver is a multi-threaded, loadable,
clonable, GLD-based STREAMS driver that supports the Data Link
Provider Interface, dlpi(7P), on QLogic qlcnic 10-Gigabit Ethernet
controllers.
The qlcnic driver functions include controller initialization, frame
transmit and receive, promiscuous and multicast support, multiple
transmit and receive queues, support for TCP Large Send Offload, sup‐
port for TCP Large Receive Offload, and error recovery and reporting.
Application Programming Interface
The cloning character-special device, /dev/qlcnic, is used to access
QLogic qlcnic P3+ 10-GigabitEthernet devices installed on the system.
The qlcnic driver is managed by the dladm(1M) command line utility.
dladm allows VLANs to be defined on top of qlcnic instances and for
qlcnic instances to be aggregated. See dladm(1M) for details.
You must send an explicit DL_ATTACH_REQ message to associate the opened
stream with a particular device (PPA). The PPA ID is interpreted as an
unsigned integer data type and indicates the corresponding device
instance (unit) number. The driver returns an error (DL_ERROR_ACK) if
the PPA field value does not correspond to a valid device instance num‐
ber for the system. The device is initialized on first attach and
deinitialized (stopped) at last detach.
The values returned by the driver in the DL_INFO_ACK primitive in
response to your DL_INFO_REQ are:
o Maximum SDU is 9000.
o Minimum SDU is 0.
o DLSAP address length is 8.
o MAC type is DL_ETHER.
o SAP (Service Access Point) length value is -2, meaning that
the physical address component is followed immediately by a
2-byte SAP component within the DLSAP address.
o Broadcast address value is the Ethernet/IEEE broadcast
address (FF:FF:FF:FF:FF:FF).
o Once in the DL_ATTACHED state, you must send a DL_BIND_REQ
to associate a particular SAP with the stream.
Configuration
Link speed and mode can only be 10000 Mbps full-duplex. See the IEEE
802.3 Standard.
